I don't want to discourage a beginner.... I'd love to see you succeed and grow strong. However, yes, this is a harder one. Additionally, these kits aren't always stocked well, and many people have run short of the threads. If you have a shop nearby, go there! Get to know the people at your LNS (sorry: Local Needlework Shop) and take classes. Start with small items and DMC thread. I'd love to teach you! But I live in NoCo. One of our group is relatively new to needlework, and we all take turns helping her...it's great to see her knowledge and confidence grow!
Holler back! I could suggest some fun projects to get you started.
